  • 2011-10-20 What to consider when buying a Knapsack sprayer?

    Written by William Taylor [Independent consultant] and Dr Andreas Herbst [JKI Germany]; formerly convenor and secretariat for the working group that prepared ISO 19932.

    Does the knapsack sprayer you are considering to buy – leak?

    Leaks are regarded by many as the most important problem of knapsack sprayers today. Tank lids, shut-off valves, hoses and their attachment points must all be effective at controlling leaks; under pressure and when the sprayer is vertical, inclined and even horizontal.

    Will the sprayer be safe and comfortable to use?

    Sprayers must be convenient to carry and comfortable to use. Check to establish it has a lifting point[s] and its fully loaded weight can be readily carried. Straps and their fixing points are critical. Wrong straps may break, come loose, be very uncomfortable and absorb spray solution. Does it also have a waist belt to both secure the sprayer in use and stabilise it when pumping?

    Can the sprayer be filled without spillage yet remains capable of filtering out debris that can clog the spray line and nozzle?

    Knapsack sprayers are normally filled with spray solutions prepared in buckets. They have to be filled quickly [typically within 60 seconds] without excessive splash or spill and with adequate filtration.
    Is the tank opening wide enough and is the filter [strainer] adequate?

    Is the knapsack stable on near level ground?

    Knapsack sprayers must not fall over when not in use. They need to be stable when placed on level ground. Does its weight distribution and design – especially its base – ensure stability? Nozzles are soon clogged and lances soon damaged on sprayers not in use. Is there a parking device for the lance when not in use that also keeps the nozzle safe?

    Is the sprayer fitted with adequate filtration?

    Poor filtration will cause nozzles to be blocked; a great inconvenience in the field that loses time and lessens safety. Are tank filters/strainers fitted to trap debris when sprayer is being loaded? Is there a pressure filter to protect the shut-off valve in the lance or a ‘last chance’ filter behind the nozzle? Can they be cleaned as and when necessary?

    Is the tank content gauge appropriate and readable?

    Accuracy of content gauge is critical to accuracy of spraying and minimising any surplus spray liquid. Often, the content gauge is not detailed enough. The gauge cannot see some spray liquids whilst other designs do not allow adequate spare tank capacity [head room] when filled to rated maximum. Ask if these needs are met.

    Will you be able to apply the water volumes and pressures that you will need for your crop protection products and crops using the sprayer you purchase?

    Sprayer output by the nozzle[s] must be within the range specified by its manufacturer. Can it be varied [within a comfortable pumping frequency and force range] to meet your needs by, for example, changing a pressure setting? Are there a pressure gauge and/or spray pressure control device to help maintain the calibrated nozzle output?

    Can the knapsack sprayer be cleaned after use?

    External and internal residual spray deposits are a threat to your safety, the next crop sprayed and the environment. Is the sprayers tank with smooth surfaces both inside and out? Are there liquid trapping points on the sprayer and is the spray liquid pick up point effectively located in tank sump? Can it spray out all the prepared solution from its tank?

    Is the sprayer robust?

    Knapsack sprayers are expected to suffer some shocks in normal use so must be capable of withstanding reasonable impact. Controlled impact tests are used to test whether the components will withstand such shock and – more importantly – allow their continued safe use. Has this sprayer design be shown to withstand reasonable impact?










  • 2011-10-20 Challenges of modern agriculture

    Given the Global context, the specific challenges of modern agriculture could be said to

    How can we continue to meet the ever growing demand for safe and nutritious food and renewable materials in the years ahead?

    How can we do this in a way that conserves natural resources and biodiversity for future generations?

    The challenges are enormous.

    At no time has the need for sustainable agriculture and sustainable agricultural products been greater. By 2030, the world’s population is expected to rise to more than eight billion people. That is two billion more than on the planet today. This poses an enormous challenge for agriculture because there is only a finite area available for farmland - it is estimated that the amount of fertile farmland per person in 2050 will be less than a third of that in 1950. Climate change brings further pressures – drought, flooding and erosion – all of which threaten fertile farmland.

    Productivity gains are essential if the world is to satisfy the demand for food and agricultural produce. In addition to adverse weather conditions, productivity limiting factors include poor soil health, lack of water, plant disease and insect attack.

    This site addresses these issues by focusing on ways to:

    · Increase production and reduce waste/loss through Integrated Pest Management

    · Protect and maintain soil health through Conservation Agriculture

    · Protect and enhance habitats to encourage Biodiversity

    · Protect water

    Soil erosion makes millions of hectares of farmland infertile every year. This means farmers must find new land, often at the expense of natural habitats. Protecting and maintaining soil health is key. Conservation Agriculture employing minimum tillage and the use of non-selective herbicides conserves the soil structure by leaving the roots intact helping to prevent soil erosion. It also benefits the farmers by reducing constant hand-weeding, while cutting the costs and carbon emissions caused by mechanized tilling.

    Nutrients washed away with the soil can also pollute watercourses and damage ecosystems. Inappropriate use of agrochemicals pollutes waterways, disrupts ecosystems and is a risk to human health. Farmers play a significant role in managing ecosystems and protecting biodiversity.

    Agriculture relies heavily on the availability of water, an increasingly scarce resource. Productivity is determined by the availability of rain and fresh water to irrigate crops. Current estimates suggest that two thirds of the world population could be subject to water stress and 1.8 billion people could be living in regions with absolute water scarcity by 2025. Sustainability is key to its management, water protection is vital.

    Conservation agriculture


    Fertile soil is the basis for growing crops.

    Millions of hectares are lost every year due to soil erosion. Fertile soil is the basis for growing crops. Looking after the soil is paramount for sustainable food production. Conservation agriculture uses a basic set of principles to protect and conserve soil in best condition for productive cropping, now and in the future. Soil degradation affects many areas, particularly with sloping ground. Loss of soil quality often forces farmers to seek new ground. This leads to the clearing of forested areas and, consequently, habitat loss.

    Conservation agriculture is based on the minimal cultivation necessary to successfully establish and grow crops. Zero tillage can be practiced on some soils; other soil types and some crops may require some cultivation to achieve a seedbed and remove soil compaction.

    The three principles of Conservation Agriculture are:

    Minimise soil disturbance

    · Minimal soil disturbance achieved through techniques of Conservation Tillage improves soil structure and soil health, with more micro-organisms and soil fauna.

    Carbon sequestration within the soil profile decreases greenhouse gases such as carbon dioxide by retaining the carbon in the soil profile.

    Keep the soil covered

    · A growing crop, green manure or dead mulch reduces wind and water erosion of soil.

    · Soil cover retains moisture and improves water infiltration. There is a need to

    · Manage cover crops and stubbles to avoid weed growth and setting seed and reduce competition with crop for water.

    Diverse crop rotations to reduce reliance on inputs

    Appropriate crop rotations can:

    · reduce the need for inorganic fertiliser

    · avoid the build up of pests and diseases thus minimising the need for pesticides

    Minimising soil tillage reduces the amount of fuel energy and time required for crop sowing. Conservation Agriculture practices can also be adopted to manage the inter-row areas in perennial crops.

    Example: Soil stability helps potato profits.

    Colombia loses an estimated 20 tons of soil per hectare every year. In extreme cases this rises to 100 tons per hectare.

    Through cultivation, Colombian potato growers traditionally move an estimated 2,000 tonnes of soil per hectare in order to achieve a yield of 15 tonnes of potatoes. Growers create a deep seedbed for planting seed tubers, and then continue to move the surface to control competitive weeds. The result leaves a fragile soil structure highly vulnerable to wind and water erosion. Colombia loses and estimated 20 tons of soil per hectare every year. In extreme cases this rises to 100 tons per hectare.

    Falling yields and uneconomic production for growers has put the future of 17,000 families at risk in the Cundinamarcia Region who are dependent on potatoes for their livelihoods. Urgent action was needed to prevent further soil loss and improve the fortunes of growers. An ongoing project was developed jointly between Corporacion Autonoma Regional, the Environment Authority, and private enterprise. The project introduced a training programme of new non-tillage techniques, innovative direct sowing and the use of cover crops to protect soil structure.

    The programme planned over 200 workshops reaching more than 4,000 small farmers across the region. Introducing growers to proven practical techniques that reduce costs, labour demands and deliver equal or improved yields creates an immediate physical benefit.

    But longer term, these activities on around 8,000 hectares of potato cropping could decrease soil loss by 480,000 tonnes over the next three years. This also increases important water retention in the drainage basin by 360 million litres.
